VISIBLE OIL PUMP.

Application led October 10, 1921. Seria1 No. 506,778.

T0 all whom may concern Be it known that we, GARDNER ROYCE, a citizen of the United States, and resident zen of the United States, and resident of Lakewood, both residing in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements 1n Visible Cil Pumps, of which we hereby de- Clare th'e following to be a. full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The principal object of the invention is to provide an improved measuring and dispensing apparatus for lubricating or other oils. Another object is to provide an apparatus 1n which the.. oil is stored and handled visibly and in which'it is also warmed and illuminated from within in such a manner as to disclose anyimpurities in the oil, such as would indicate that the oil had not been filtered, and'which would also indicate the grade of the oil by disclosing the exact color thereof, the grade being determined commercially by thecolor. A further object is to provide for the visible dispensing of oil whereby the, purchaser can determine that he is receiving full quantity as well as satisfactory'quality. of the same.l Other'objects will appear in the course of the following description.

The device comprises a tank, having part of its wall portion transparent. Within the tank is secured a heating element, which is also preferably illuminating. This element may be an electric light bulb, which is enclosed in a transparent case or tube containing air, in which the bulb is enclosed.

The light from this element traverses the oil in all directions and discloses the color of the oil and all impurities therein. A heating element that does not illuminate may be employed, if desired.

The invention further comprises the combination and arrangement of parts and construction of details hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, the single figure vshown is a vertical longitudinal section of the device.

In this figure, 1 is a container or tank, provided'with a cylindrical glass intermediate section positioned between a palr of metallic heads, 2 and 3, held together by -means of -clamping rods 4; packingrings,

in the head, 2, and from an insulated socket,

11, conductor lwires 12, 12, lead to a lamp bulb, 18, or other heating and illuminating element. suspended in the inner tube. The air in the inner tube separates the heating the oil, so that the heat of the lamp and possible .short circuiting and resulting sparking will result in no danger through fire or explosion.

A valuable feature of the invention lies in the fact that the mild heat transmitted or radiated from the lamp or other heating element, will prevent the oil from congealing in cold weather to such an extent as to permit it to flow freely through the outlet opening, 14. 15 is a stand pipe through which oil is supplied to the container 1. 16 is a cut oft1 valve therefor. This 'stand pipe forms the usual support for the oil tank at gas station.

The oil is admitted to the container..

through the conduit provided bythe stand pipe 15 until the container is completely filled, the valve in the outlet conduit 14 being in closed position. The valve 16 in the stand pipe is then closed and a measured quantity of oil is visibly displayed .in the vcontainer and is ready for dispensing through the opening of the valve in the outlet conduit, through which it flows by the force of gravity.

maybe forced. into the containerthrough The oil supplied through the stand pipe and illuminating elements from the body of the use of compressed air or by means of a mechanical pump of standard design.

lHaving described the invention, what I claim as new, and desire to secure by Letters Patent, is:

1. AAn apparatus of the character vdescribed having 1n combinationl a transparentv measuring and dispensing chamber, means for supporting said chamber at an elevated position, means for supplying liquid to said chamber under pressure, means for discharging liquid from said chamber through force of gravity, and an illuminating and heating element disposed within said chamber.

2. An apparatus of the character described having iii combination a transparent measuring and dispensing chamber, a second transparent chamber disposed within said first named chamber, and an illuminating and heating element housed within said inner chamber.

3. An apparatus of the Character described 'having in combination a transparent measuring and dispensing chamber, means for supporting said chamber at an elevated position, a second transparent chamber disposed within said first named chamber, an illuminating and heating element housed within said inner chamber, means for adr mitting oil into said first named chamber through said supporting means, and means for permitting oil to flow from said chamber by force of gravity.

4. In a filling tank for a gasoline station, a transparent cylinder, upper and lower heads therefor, a stand pipe upon which said lower head is supported, said stand pipe communicating with said cylinder, an outlet passage leading from said lower head, valves for controlling the inlet and outlet of oil,

V and electrically operated means for illuminating the oil in said tank to disclose the color thereof and impurities therein.

5. In a lling tank for a gasoline station, a transparent cylinder, upper and lower heads therefor, a stand pipe upon which said lower head is supported, said stand pipe communicating with said cylinder, an outlet passage leading from said lower head, valves for controlling the -inlet and outlet of oil, and electrically operated means for illuminating the oil in said tank to disclose the color thereof and impurities therein, said electrically operated illuminating means serving also as a heating means to prevent the congealing of said oil.

6. In a filling tank for a gasoline station, the combination with a stand pipe, a lower head thereon, a transparent cylinder, and an upper head, means for securing said cylinder between said heads, said lower head being provided with an inlet opening communicating with said stand pipe, and with an outlet opening valves for controlling said openings, said upper head being provided with a central opening, atransparent tube depending from said upper head, a cap over said opening, and an electric lighting bulb depending from said ca within said tube substantially as described? In testimony whereof, we hereunto set our hands this day of September 1921.
